The two extensions mentioned use YAML also because form extensions have a history in Neos that uses YAML, and ckeditor uses YAML itself.
At the core of the kernel there are no plans to completely abandon TypoScript, however, YAML has some advantages that are very important:
- It is a configuration language known and used in the outside world of TYPO3
- It has well-known parsers and tests.
Therefore, it is possible that new configurations may be made in YAML.
Especially with the use of Fluid, ViewHelpers, the use of TypoScript has fallen - at least for me - a lot, and I am very happy about that. However, page.10 < styles.content.get will remain for a while;)
